Application filed June 20, 1928. Serial N0. 646,730.

- ture on stock or machinery often cause heavy losses. Humidifiers as ordinarly used forcibly eject moisture into the atmosphere of the room without providing for its diffusion and regardless of the fact that air can only carry in suspension a definite amount of moisture; hence supersaturation in the neighborhood of the humidifier and a consequent deposit of moisture will necessarily result.

My invention comprises a specially constructed atomizer requiring no water pres sure and a very low air pressure and is constructed to provide in addition a sutlicient volume of continually flowing unsaturated air which is thrown from below into the atomized stream, supporting and diffus ing itthrough the room, thus preventing.

oversaturation in the vicinity of the apparatus. As a result of the use of my apparatus the finely atomized water or other liquid will directly impinge on a moving current of air and be more or less taken up by it and carried away to change the condition of the atmosphere. The air and water are not brought in contact in the machine but outside of it and are easily controlled so that any desired condition of the atmosphere can be controlled by controlling the air-moving elements of the machine.

My invention will be understood by reference to the drawings in which it is shown in its preferred form.

1 is a casing comprising side walls, a flooring and a cover to keep out dust and the like. 200 is a flooring on which is supported an electric motor 3 of ordinary construction having a shaft 4: on which is mounted the rotor of the air pump 5 which is also of any usual construction and is supported on the flooring 201. A blower fan 6 is mounted on the outer end of the shaft 4. On the floor of the casin is the movable pan 2 of proper size to catcl i any oil drippings.

The purpose of the pump is to supply air to the atomizers and this it does through the pipe 7 on the top of which is mounted a pressure gauge 8. An elbow 9 connects this pipe with an enlargement thereof 10 from whicha pipe 11, made preferably in sec tions as shown, runs-into a drum 12. As it is desirable that the air supplied to the pump 5 shall'be as clean as possible it is supplied by the pipe 275 shown in elevation in Fig. 3, its upper end curving over as shown in dotted lines in Figs. 1 and 7 and if neces sary provided with a strainer of some suitable kind.

13 is an oil cup which is connected by the pipe 14 to lubricate the air pump. Provision is made to prevent any lubricant from reaching the atomizers by the pipe enlargement 10 in which the air may expand slightly and drop the lubricant, which the air may carry from the pump, such lubricant being led off by the pipe 19 controlled by pet cock 191.

As a certain amount of lubricant may still be retained in the air or air passage, provision is made to eliminate it by two baffles 20 and 21 contained in the drum 12 to which the enlargementlO is connected by the pipe 11. From the pipe 11 the air passing into the drum impinges on the baffle 20 the lower edge of which is notched, then through the notches and up between 20 and 21 leaving most of the lubricant which it may carry behind it. The bafile 21 is provided with a hooked edge or wiper 23 and drum which may be removed when necessary to drain the oil from the drum. These closures also serve as a means of supporting the drum on two brackets 25, which are mounted on the water tank 26.

27, 27 are small tapering pipes each leadin g down into the water, stopping preferably at some point between the bottom of the tank 26 and the normal water level 29, the upper end of each being provided with a nozzle 28.

in practice. I prefer to attach the upper end of each water pipe 27 to a carrier 41 which as shown is hung on the pipe 221 which carries the nozzle 22 of the atomizer. Each nozzle proper 22 is formed in a cap 220 which screws onto the end of the pipe 221 extending from the drum 12. The carrier 41 has an upward extension 42 having an opening t-herethrough, through which passes the pipe 221. In a passage 43 through this extension is located a spring 44 which is adjustably held in the passage by a screw plug 45. the upper end of this spring resting against the under surface of the pipe 221. Through the upper portion of this extension passes a set screw 41; the lower end of which rests on the top of the pipe 221 so that the pipe is held between the spring 44: and the screw 46 and within certain limits the position of the nozzle and tip of the pipe 27 may be adjusted with relation to each other to secure the desired spray. The tank 26 may be filled and kept full of Water in any common way either automatically or by hand. I have shown two atomizers one near each end of the device, but any length of drum may be used with a corresponding number of atomizers and fans.

As stated above, the tendency of sprays is to fall to the floor. To prevent this I provide ablower having a specially constructed air-directing battle which not only delivers air to receive and absorb the sprays, but also spreads them in such a way as to produce complete diffusion through the room. This device which I will call an air distributor is designed first, to correct the spiral air delivery common to all suchblowers; second, to diffuse and deflect the air without impeding its velocity so that it will drive into the atomized sprays mixing therewith and assimilating some of their moisture, and by its force diffusing a current of properly conditioned air substantially throughout the room.

This air distributor is located in the end of the casing 1. in front of the blower fan 6 which is set into an opening in the wall which divides the front end of the casing from the rear end in which is located the pump and the motor. In front of the blower fan 6 is located a box 40, the side walls. of which slant inward toward the periphery of the fan, and within this box are mounted a series of vertical battle plates 32 and 33 all held in place by rods 34. The bottom of the spaces between these battles is formed by a series of curved plates 400 attached at their lower and inner ends to the floor of the box and projecting forward and upward. One side of each plate being higher than the other and registering with the adjacent side of the plate next it so as to have the effect of a curved continuous flooring extending upwardly from one side of the box 40 to the other, but broken by the baflles 32 and 33 and the bafile plates all swing to cause the blast of air to be guided upwardly and lift the atomizedjets thrown from the nozzles. The front of the box 40 is somewhat in rear of the front wall of the tank 26 which is preferably slanting so as to direct the air which strikes it from the blower and box upwardly.

It will be noted that one bafile 33 of the ballie plates extends nearer than the others 32 to the face of the fan. This divides the current of air into two substantially equal blasts. The location of this battle off the centre of the fan secures better results than if it be located in. a plane with the axis of the fan. It has been found that in its rotation a fan of this kind tends to throw the air not out in lines parallel to its axis but to one side of the axis in a swirl so that the air will be crowded over to one side of the box, say to the left side of the box (see Fig. 4). By using a battle like 33 which approaches the fan quite closely and is located to the left of the axis of the fan looking from the front, the crowding of the air referred to is {prevented to a large degree and by locating a number of baffles 32, 33 as shown the swirling of the air is prevented and it is thrown out from the fan in approximately a straight line until it is deflected upwardly by the floor against the slanting wall of the end of the tank so that it is given an upward and outward direction which carries it into the spray from below, supporting the moisture and carrying it along, thus diffusing it throughout the room.

This same result may be otherwise socured, and I do not mean to limit my invention to the exact construction shown.

What I claim as my invention is 1. A humidifier comprising an air nozzle discharging air under pressure, a liquid nozzle and a liquid tank and connections between said liquid nozzle and said tank, said air nozzle being located with relation to said liquid nozzle whereby the air from said air nozzle will draw up and atoinize liquid from said tank through said liquid nozzle and will mingle with said atomized liquid, in combination with means comprising a blower located below said liquid nozzle and means whereby the blast from said blower will be directed to and discharged under said atomized liquid whereby said atomized liquid will be carried by said blast and diffused.
